Cracked window on 305

I cracked the front window on a Cat305CCR. It has about 15 cracks going out from the center and while I can see out, would really like to replace. What is the best route to replace without ordering through CAT.

One of my guys broke the door glass on my 304D. I ordered it from Cat and had a glass company install it but it was curved glass. I think it was only a couple hundred dollars, I thought it was going to be a lot more than that.
